This is the most beautiful hike we did. Took the bus from El Chalten to El Pilar and started our day from there. The weather was beautiful and we had a blast. Our independent recordings of the trail showed a longer distance (15.3 miles), but it is true that once we got up, we continued the exploration around the laguna. I was very tired and I had to take some Ibuprofen to help with my feet pain (I have a severe plantar fasciatis). Wonderful hike!!!!
